IMPROVEMENT IN STOVE-GRA'I 'ES.

Specification forming part of Letters Patent No. 33,919, dated December10, 1861.

To all whom it may concern.-

Be it known that I, J OHN MAGEE, of Boston, county of Suffolk, and Stateof Massachusetts, have invented an Improved Grate for Stoves, &c. and Ido hereby declare the same to be fully described in the followingspecification, and representedin the accompanying drawings, of which-Figure 1 denotes a horizontal section of a stove taken in a plane justabove the grate;

Fig. 2, an end view of the stove, showing the.

rocker-lever; Fig. 3, a top view of the grate as removed from the stove.

The nature of my invention consists in so constructing and applying thegrate of a stove to the lower part or plate of the fire-chamber andconnecting therewith certain mechanism, as hereinafter described, thatwhen such grate is put in operation two separate mechanical movementsmay be obtained viz., a rectilinear horizontal one and a rockingvertical one-the same allowing not only the coal in the fire-chamber tobe'soreened without causing the ashes to escape into the room, but alsopermitting the coal to be dumped into a receiver placed in theash-chamber Whenever the same may be required.

In the drawings, Adenotes the body of the stove, while B is the lowerplate of the firechamber.

O is the grate, which is composed of a rectangular frame D and a seriesof transverse bars a a a.

D D are two horizontal guards arranged at the two ends of the grate, asseen in Fig. 3. These guards are placed close against the ends of thegrate-frame, so as to prevent any pieces of coal from falling betweenthe grateframe and the lower plate of the fire-chamher during theoperation of sifting the ashes from such coal. The said guards aredisposed on the under side of said plate and so as to slidelongitudinally thereon, one of the said guardsviz., D' being guided inits movements by flanges 12 b, as shown in Fig. 3,

while the other guide is controlled in its of a projection or flange (Z,arranged as seen in Fig. 1. The pivot c is formed With a notched head 6,the notched portion being formed rectangular in cross-section, the samebeing so as to receive a rocker-lever f, which serves, in connectionwith a slot g, formed in the hearth h of the stove, to impart therequisite motion to the grate While performing the operation ofscreening the coal, &c.

Although I have described the grate as made in one piece, I would remarkthat it may be formed in two pieces and have one part of the samecapable of being turned in a Vertical direction, so as to dump the coal,the said grate under such circumstances being formed somewhat longerthan in the first case, so as to extend entirely underneath the lowerpart of the fire-chamber, the end bars of the grate serving asguard-bars. Fig. 4: represents this modified form of grate.

In the operation of my said grate, if we suppose the fire-box to befilled with coal and ashes and we desire to screen the coal, we haveonly to move such lever f back and forth in order to impart alongitudinal movement of the grate, which will readily cause the ashesto fall into the ash-chamber. Then, if we desire to remove the coal fromthe grate, we have simply to remove the rocker-lever from its step orslot and turn it toward the front or the stove, and We shall haveaccomplished our object.

A grate constructed in the above-described improved manner is not onlyvery simple in its construction, but is very etficient in its operation.

I do not claim, broadly, arranging a grate below the fire-chamber of astove so that such grate may have either a rotary movement or a verticaltilting one, as I am aware that such is not new; but

What I claim is Combining and arranging together the rectangular grate Cwith the guard-plates D D and the ways I), so that the grate can notonly be rocked on its pivots 0 but be moved in the direction of itslength, substantially as above described.
